The Homage-o-Meter is an extra on the Spaced DVDs. A caption will appear every time a pop culture reference is made whether it be film, music, TV, art, sound effects, literature, or whatever and tells you what the reference is exactly. There are many and 133 are films, although there are a bunch that are referenced more than once. However, there are still 95 films I have to watch so as you can tell, this is a long term project. Both for me and any followers.
